My system is not decent

Chapter 1141 The key
As long as a piece of silver rabbit hair can be fired successfully, it will be easy to talk about in the future.

If there is one, there are two, and I am afraid that one will not be fired successfully.

As long as you have the first one, it means you are on the right path.

As long as you do more and more, accumulate more experience, and control the temperature more and more accurately, there will be more and more successful works in the future.

After that, even if there are not many successes in one kiln, or even only a few pieces, it is still a success.

Besides, he doesn't need to fire them in large batches, and it is already very powerful to be able to successfully fire one or two pieces in one kiln.

This is the difficulty of controlling kiln changes. Often the process between firing and failure is only a few seconds, which is too difficult to grasp.

Fortunately, modern technology and equipment are very powerful. Although it is still impossible to accurately grasp the firing atmosphere, it is still possible to check the situation in the kiln.

And as long as it is detected, the firing conditions are about to be reached, and if manual intervention is performed at this time, the success rate will be relatively high.

After all, Chen Wenzhe's kiln firing technology is not a boast.

Therefore, it is better to think about the difficulty in the process of burning the silver rabbit hair again.

It's just that among the rabbit hair cups, there are more than just silver rabbit hairs.

When firing silver rabbit hair, sometimes the temperature in the kiln is not accurate, but other rabbit hair lamps, even oil dripping lamps, can be fired by accident.

Here is a little mention of the oil drop cup. The mechanism of the formation of the oil drop cup can be summarized as the duckweed mechanism.

When fired to about 1300°C, under specific physical and chemical conditions, the glaze begins to form a liquid phase separation structure, and the main phase of the glaze separates into another iron-rich phase.

Under the action of gravity and surface tension, the iron-rich phase is easy to float on the glaze surface layer, and as the process goes on, more and more iron-rich phases float on the glaze surface.

The liquid phase droplets formed by these iron-rich phases are like green weeds floating on the water surface and can swim on the liquid surface.

They meet randomly, in groups of three or five, and piece together into parcels of different sizes.

The larger the package, the more liquid phase droplets in it, but these liquid phase droplets are only close together.

At this time, these droplets are not fused together, just like a leaf Qingping leaning together.

After firing to a certain extent, lower the temperature and cool down.

During the cooling process, when the environmental conditions are suitable for the crystallization of iron oxides in the package, a drop of kiln building oil is formed.

Therefore, the oil dripping lamp is formed at the last critical moment. Of course, the firing temperature and the change of the glaze are also the key points.

In any case, as long as you can fire the rabbit hair cup, and grasp a few key points, you will definitely be able to fire the oil dripping cup.

And in a last-minute change, the oil droplets can also be divided into several categories.

Such as gold oil drop, blue silver oil drop, red oil drop, iridescent oil drop, etc.

In this way, things are more wonderful, because here appear the colors of gold, blue silver, red, iridescent.

Then, can burning paper rabbits make out these glaze colors?

In fact, the colors of all kinds of porcelain are related to each other, just like iridescence. If you change it a little, you can make a needle-like scene that radiates like a rainbow. Isn't this Liuxia lamp?
And the radiant decoration of Liuxiazhan, isn't it the same as the hair of a rabbit?
Among the porcelains here, only the kiln decoration inside the bowl is different. The appearance of the oil drop bowl is due to the small oil droplets appearing in the inner glaze layer.

And the rabbit hair bowl is because after the successful firing, the scene in the bowl is like the needle-like radiation of various colors like rabbit hair.

Although the appearance of the two kilns is different, they are fired from the same material. If the temperature and cooling are well controlled, the glaze color formed by the oil drop lamp can also be achieved by the rabbit hair lamp. After all, the color is formed by iron elements.

At this time, Chen Wenzhe had more ideas about the firing of the kiln, or the control of the temperature.

As time went by, he learned more and more about Tu Haozhan.

There are only a few shapes. To be honest, the shape of rabbit hair can be divided into length, thickness, etc., and the color can be different from gold, silver, etc.!
Even more precious, the most difficult to obtain should be the blue rabbit hair.

If the induction is more comprehensive, there are really many colors of rabbit hair Jianzhan.

The classic colors of rabbit hair can be divided into gold rabbit hair, silver rabbit hair, blue rabbit hair, green rabbit hair, yellow rabbit hair, red rabbit hair and so on.

Among them, silver rabbit hair or silver blue rabbit hair are relatively rare, and the difficulty of firing is relatively high, which is often more precious than other colors of rabbit hair.

But this is not absolute, it depends on the distribution uniformity and density of the lines, as well as key parameters such as the clarity of the lines.

To judge the value of a rabbit hair Jianzhan, you can't judge blindly based on the color.

Generally, it is not difficult to make a rabbit cup, for example, it is not difficult to burn a yellow rabbit, a green local tyrant, and a red rabbit.

These colors are all colored by iron elements. When firing other precious rabbit hair, if you can't control the temperature, it is possible to fire these three colors of rabbit hair.

Therefore, the most difficult thing to burn here is the silver rabbit hair. On this basis, if the grasp is not accurate again, you can accidentally burn golden rabbit hair, yellow rabbit hair, etc.

If the silver rabbit hair is fired, then you can go one step further and burn the blue light silver rabbit hair.

As long as you are a little knowledgeable, you should know that if you fire Jianzhan, the more unstable the precipitation process is, it can be said that this kind of crystal is difficult to fire.

Therefore, it can be said that silver stripes are more precious than brown stripes, and it is even rarer if silver has blue light.

And it doesn't seem too difficult to achieve this effect.

Of course, this is something that the hard-pressed will not do.

In ancient times, people couldn't figure out the truth at all, just like a blind man feeling an elephant, naturally he could only try his luck.

Modern people are different, as long as they understand the distance, it is not too difficult to restore a specific kiln transformation.

This is for Chen Wenzhe. Without a solid foundation and a strong foundation, no matter what kind of kiln-shaped porcelain is fired, it will be very difficult.

At this time, he has already been able to control the firing of rabbit hair lamps, even for some rare kiln changes, he can also have a high probability of controlling the kiln changes.

This is more powerful, but he can really do it.

At the very least, after firing a few kilns, one or two pieces of blue rabbit hair can be successfully fired.

The reason here is also very simple. If the reducing atmosphere in the kiln is strong, the content of magnetite crystals in rabbit hair grains is relatively high.

At this time, the crystal size is larger and grows parallel to the glaze surface, which has a strong metallic luster and forms silver rabbit hairs;
If the oxidizing atmosphere in the kiln is strong during firing and the content of hematite crystals in Tuhaowen is high, two situations will occur again.

If the crystal size is small and grows randomly without reflection, yellow rabbit hairs will be formed;

If the crystal size is large, grows parallel to the glaze surface, and has a strong metallic luster, it will form golden rabbit hairs.

In other words, even if you fail to make silver rabbit hair, you may be lucky enough to get yellow rabbit hair, and if you are even more lucky, you will get golden rabbit hair.

Therefore, even if you have a thorough understanding of the firing process of Jianzhan, sometimes it depends on luck.
